 Posted: Wed Dec 23, 2009 4:12 am Post subject: [SOLVED] Strange problems with exported function... |
 |
|
Hi, I've some problem with this function.
I'm using it by exporting from User prx to Vsh pbp,
it works for directory with no more than 2 subdirectories, otherwise it crash...
I can't undestrand why, probably something stupid, but maybe not....
I've thing that it could be a stack overflow but I've tryed to increase the calling thread stack and it still doesn't works...
| Code: |
SceUInt64 XioDirSize(char* Dir)
{
return XioDirSizeFunct(Dir, 0);
}
SceUInt64 XioDirSizeFunct(char* Dir, SceUInt64 Size)
{
int dl = sceIoDopen(Dir);
if(dl < 0)
return 0;
SceIoDirent sid;
char Fullname[256];
memset(&sid, 0, sizeof (SceIoDirent));
while(sceIoDread(dl, &sid) > 0)
{
if((strcmp(sid.d_name, ".") == 0) || (strcmp(sid.d_name, "..") == 0))
continue;
sprintf(Fullname, "%s/%s", Dir, sid.d_name);
if(FIO_S_ISDIR(sid.d_stat.st_mode))
{
XioDirSizeFunct(Fullname, Size);
}
else
{
Size += sid.d_stat.st_size;
memset(&sid, 0, sizeof (SceIoDirent));
}
}
sceIoDclose(dl);
return Size;
}
|
A question, exported functions use the calling thread stack?

Two points
1. You calculation is wrong | Code: | if(FIO_S_ISDIR(sid.d_stat.st_mode))
{
XioDirSizeFunct(Fullname, Size);
}
|
should be | Code: | if(FIO_S_ISDIR(sid.d_stat.st_mode))
{
Size = XioDirSizeFunct(Fullname, Size);
}
|
2. I don't know if this matters but you didn't memset sid after getting "." or ".."

Yes, I know ( for the 1st point ), I've tryed before to do it with a pointer, and I haven't added "Size = ...".
For the 2nd, I'll try but I don't think that can be that...
Sorry for my english,

Can't use psplink, have no memory...
There's a way to install exception handler on 5.xx fws?
